  1. I managed to get the later rear brake caliper onto my '99 315. It's a while ago now but I think I only had to file a bit off the built in axle spacer. A few careful measurements did the trick.
  2. When you get some info, might I suggest you try D Faulkner springs for a bespoke poundage, they're sure to be cheaper than a generic heavy duty one off the dealer's shelf... Or just copy one.
  3. As previously said, be firm and positive or you may find your knee cap embedded in the renthals. I have the much unwanted t shirt, several times !

    Very nice indeed.

    Mecatecno 326

    Sold on and then restored 20 odd years later by Mark Kremin, see the bike further down the page.

    Yes it is. And don't forget to take care with the positioning of the kickstart lever, if I remember rightly a 1oclock position, at rest, will save your crankcase from being internally holed. Once done you'll not make the same mistake again, no matter how practical it may seem !
  7. Many years ago there was a chap who used the very plush Fournales air shock to convert a Bultaco or two. No linkage, which was the same as the JCM bikes.

    Air box plastics

    It's a bit late now but I've always drilled a hole 2/3 mm, or bigger depending on the crack, at the end of a split in plastics, be it mudguards or polycarbonate windows. It's usually stopped the progressing split dead in it's tracks.
  9. I've chucked a set of 2nd hand 40mm alloy marzocchi forks and yolk on mine. I'd found the same issue as you. They're much lighter as an added bonus.
  10. It does sound like the key's sheared. An easy investigation and fix if it is.
  11. I'm not being funny but if you're going to 'reject' it then I wouldn't be pulling the engine covers off. Any business would say you've been messing with it ?

    Beta 4t carbu

    Surely this boils down to the float valve and seating. I can't remember if a neoprene seated valve would be available ?
  13. I remember having a John Shirt 270 conversion / rebore. For me, it was a major improvement in the engine department, a bit more torque and still a nice smooth power delivery. Just a thought if it's still available nowadays.

    Cota 248 wheels

    What about mounting the hubs then use a plumb line from the centre of the rear frame, a bit of careful measuring should give you the required numbers.
  15. Perhaps the silencers are that clogged up with oil ?
